' iMPROVEMENT iN OIL-BOXES FOR RAILROAD-CARS.

fi 'iecificaiion forming part of Letters Patent No. 412,?32, dated May10, 1864.

To all nhomit may concern Be it; known that we, EDWIN F, HURLBUT andRansom S. Porrns, of the city of (311ici-go, county of (3001;,and Stateof Illinois, have invented new and useful Improvements in Oil-B'oxes'forRailway-Cars; and we do hereby declare that the following is a full,clear, and exact description of the some, reference being had to theannexed drawings, making apart of this specification, in which- .lligurel is from; View of box complete in it place in iron frame with a springover it. jhig. 2 is a side view of Fig. i. Fig. 3 is cross'scction ofFig. 2 through lines A B. 6 is transveri; section of Fig. 1 through 5 isthe ions of of the hinges lines 13 D. Fig. the hack. of tho cover,

lho nntuieor" our invention consists in making a. (lo in the cover orlid of the oii-hox,hy which-means the inside of the ex can he examined,the journal of the axle .seen, the wasic picked or loosened up, and

ihc box filled with oil, without taking off the cover, and at ihe sometime having the (loorso mule as to prevent it'ii'om getting loose orwearing out because of the iar oo- Oil-SlODBll hy the motion oi thecar's' in running; also, by making the logs or cars of-the oilbox loose,so that they answer the purpose also of a jaw, in which the box mayslide, thus preventing the great wear and loss of bolts 1 consequentupon the mode heretofore pracgiced, anclfor other reasons, morefullyhcreinafter described.

To enable those skilled in the art to fully understand anal constructour invention, we will proceed to describe ii.

The cover-frameA,Figs. 4 and 5,isfirst cast, having, by means of a coreor other device, a slot out in it to receive the hinge of the door, andby means of the core which forms the slob forming at same time in eachend ofthc cover- -fraine this out, an indentation, as shown in Figs. 2,el, and 5, by clotted lines I) and more folly in Fig. 5,}, the shapepreferred by us being that of aconic seoiion three-eighths oi an inch atbase and some in depth. Others may prefer different sizes. Thecover-frame thus made is then molded with the pattern of the door,

and remainsin the mold after the door-- pattern is drawn. When the moldis filled with the molten iron, the indentations heretofore described inthe cover-frame are filled; also,

thus making upon'each side of the hinge of the door a. small cone, whichholds the door firmly in its place in the cover-frame. Upon each side ofbox there are two strips cast, Figs. 1,2, and 6, letter d, which are toact as guides to hold the box in its proper place in the truck-trams"ainst the lugs, and by means of said st s or their equivalent allow ihchex when ussil iih. a spring upon I, a he lugs. The -otlcr D, shrsilrlwe space. rho enilof vcrlyic i 1 ,0 being greater or less accoari; ofbox used. with or WihlliOEJ-i) spring Th advantages claimed an derivedby this mode of making oil-box's, are, first, that'hy use of the door inthe cover the labor of the men who at present'tako ofi and replace thecovers for the oiler are entirely (lispensed with; also, that under thesystem heretofore in use there are-large losses of bolts and covers byreason of the continual wear occasioned by so frequently taking out andreturning the bolts, which losses are entimely-obviated by use of theimproved cover, thereby making a large saving to railroads in the courseof a year; second, that by use of the loose lugs or ears,letter D, thegreat wear in all! iron truck-frames, and. consequent loss of boltsnecessary to retain the box with lugs or cars cast on them in properposition, is saved also,'in cases requiring a pair of wheels to removedfrom the truckhy taking outthe bolt; front of the box on each end. ofthe axle,- the wheels can be taken away, while in trucks as heretoforemadcall-the bolts have to be removed, which allows the iron frame toseparate, making greatinoonvenienoe, as also waste of labor in replacingthe same; also, by use of loose lugs we are enabled to place the springover the box in iron truck-fra1nes,which cannot he done excepthyincreased expense under the plan lmrei'oflvre in use, all of whichwill efl'eut large snynws to railroad companies.

Having thus fully dvscrihed ur invention, we do no claim the particularplace or manner in the frame of fastening the door, for the conicalpoints and indentions may be received, or tlw IlOOIIl1;I be cast upon awire in the frame; but

What; we do claim as new, and desire to secure by Letters Patent, is

1. Casting or fastening a door or lid into a frame, substantially asshown, and for the purposes described.

2. Thcomhination oi'the loose lugs or eaz s, letter 1); with theoil-110x, substantially as shown, ilnd for the purposes described.
